It is clear that we are in touch with some entirely new form both of matter and of energy. We know little of the properties of this extraordinary substance save that in its materialising form it seems extremely sensitive to the action of light. A figure built up in it and detached from the medium dissolves in light quicker than a snow image under a tropical sun, so that two successive flash-light photographs would show the one a perfect figure, and the next an amorphous mass. When still attached to the medium the ectoplasm flies back with great force on exposure to light, and, in spite of the laughter of the scoffers, there is none the less good evidence that several mediums have been badly injured by the recoil after a light has suddenly been struck by some amateur detective. Professor Geley has, in his recent experiments, described the ectoplasm as appearing outside the black dress of his medium as if a hoar frost had descended upon her, then coalescing into a continuous sheet of white substance, and oozing down until it formed a sort of apron in front of her.

This process he has illustrated by a very complete series of photographs.
These are a few of the properties of mediumship. There are also the beautiful phenomena of the production of lights, and the rarer, but for evidential purposes even more valuable, manifestations of spirit photography. The fact that the photograph does not correspond in many cases with any which existed in life, must surely silence the scoffer, though there is a class of bigoted sceptic who would still be sneering if an Archangel alighted in Trafalgar Square. Mr. Hope and Mrs. Buxton, of Crewe, have brought this phase of mediumship to great perfection, though others have powers in that direction. Indeed, in some cases it is difficult to say who the medium may have been, for in one collective family group which was taken in the ordinary way, and was sent me by a master in a well known public school, the young son who died has appeared in the plate seated between his two little brothers.
As to the personality of mediums, they have seemed to me to be very average specimens of the community, neither markedly better nor markedly worse. I know many, a nd I have never met anything in the least like "Sludge," a poem which Browning might be excused for writing in some crisis of domestic disagreement, but which it was inexcusable to republish since it is admitted to be a concoction, and the exposure described to have been imaginary. The critic often uses the term medium as if it necessarily meant a professional, whereas every investigator has found some of his best results among amateurs. In the two finest seances I ever attended, the psychic, in each case a man of moderate means, was resolutely determined never directly or indirectly to profit by his gift, though it entailed very exhausting physical conditions.
